Average Power Calculator

Average Power Calculator

The Average Power Calculator is a tool used to calculate the average power consumed in an electrical circuit.


The formula for average power is:

Average Power = (Root Mean Square Current)² × Resistance

To use the calculator, input the values of the Root Mean Square Current (irms) in amperes and the Resistance in ohms. Upon clicking the “Calculate Average Power” button, the calculator will compute the average power consumed and display the result.


Let’s say we have an electrical circuit with an irms of 2 amperes and a resistance of 10 ohms. Using the formula, we can calculate the average power as:

Average Power = (2 amperes)² × 10 ohms = 40 watts
